Nadhim Zahawi: I am grateful for my right hon. Friend’s important question. We have received interim advice from the Joint Committee on Vaccination and Immunisation, which we have published, and it has now received the Cov-Boost data. The interim advice was about vaccinating the most vulnerable with a booster for covid and for flu. It is advising a two-stage process, and stage one is to offer the booster vaccines to those in the old 1 to 4 cohorts plus the immunocompromised, and then to groups 5 to 9. That is the right way to  proceed. We have not yet received its final advice. It could be different to the interim advice, but boosting preparations are well under way. Clearly that final advice is predicated on which vaccine delivers the highest level of protection and durability.
